ABTHUR I. ECHTERNACH, OF SEATTLE, WASHINGTON.

PATENT OFFICE.

AUTOK ATIC SPEED-SIGNAL DEVICE.

Application filed January 11, 1921. Serial No. 436,486.

To all whom it may concern Be it known that I, ARTHUR M. ECHTER- Nixon,a, citizen of the United States, andv residing at Seattle, in the countyof Kin and State of Washington, have invented certain new and usefulImprovements in Automatic Speed-Signal Devices, of which the followingis a. specification.

This invention relates to an automatic speed indicator for vehicleswherein visual or audible alarms are operated at predetermined vehiclespeeds, so that both the driver and any other interested party may knowwith more or less accuracy the speed at which the particular vehicle istraveling.

The invention is directly controlled by the speedometer and theoperative parts of the invention may he set in any one or more,preferably three. predetermined speeds, so that when the machine istraveling and the speedometer indicates the particular speed or speedsfor which the device is set, the alarm or alarms will be automaticallyoperated to indicate the fact of such predetermined speed or speeds.

The device in the preferred form is arranged with visual signals, forinstance, three in number, the first of which will indicate a minimumpredetermined speed, the second of which an intermediate predeterminedspeed, and the third of which will indicate a maximum predeterminedspeed. This form of the device is operated electrically so that as thevehicle travels through the successive predetermined speeds, the alarmswill be operated in succession to indicate such speeds.

A modified form of the device is operated mechanically to sound anaudible alarm or alarms with exactly the same result as that describedin connection with the visual alarms.

In the drawings:

Fig. 1 is a broken perspective view il' lustrating the application ofthe invention to a dash board of a vehicle.

Fig. 2'is a viewillustrating more or less diagrammatically the preferredform of the invention.

Fig. 3 is a broken rear elevation of a vehicle showing the rear signalbox applied thereto.

Fig. t is a sectional view showing the arrangement of the contacts inthe speedometer.

Fig. 5 is an enlarged horizontal section through the rear signal.

Fig. 6 is a vertical section through the same.

Fig. 7 is a view in elevation partly in section of a modified form ofdevice.

Fig. 8 is an elevation of the actuating means used in such modifiedform.

' Fig. 9 is an elevation of a signal mem ber used with the modifiedform.

Fig. 10 is a plan showing an arrangement of contact strips to indicatesubstantially all speeds between certain limits.

Fig. 11 is an edge view of one of such strips to indicate thenon-contacting portion thereof.

In carrying out the detail of the invention in connection with thepreferred form as illustrated in Figs. 1 to' 6 inclusive, thespeedometer dial 1 is provided with concentric spaced strip-likecontacts 2, 3, and 4. These contacts which are insulated from the dialare arranged in concentric spaced relation and while their relativelengths may be such as described in accordance with the signallinglimits of the device, they are shown in the present instance as aligningrespectively at their entrant ends with lines radial of the disc andcoinciding with the 20, 30 and 40 mile mark on such disc. The oppositeor remote ends of the contact strips terminate in a line radial of thedisc and coincide with the maximum mileage indication of the disc. Thespeedometer pointer 5 which is insulated from the disc, is provided withcontacts 6, 7, and 8, which in the speedometer operation of the pointerengage respectively with the strips 2, 3, and 4.

On the dash 9 of the vehicle are, in the particular arrangement beingdescribed, secured in any appropriate manner three elec tric lights 10,11, and 12, which, may be differently colored or which may be marked toindicate the initial mileage indication of the strips 2, 3 and 4respectively. A rear signal casing 13 is mounted at an appropriate pointon the rear of the vehicle and is rovided with an offset having the taillig it 14 therein and with a horizontal portion having electric lights15, 16 and 17 marked in correspondence with the dash lights to indicatethe initial mileage indication of the strips 2, 3 and 4. That is to say,each strip controls a light on the
